This invention relates to curtain rails of the kind comprising a slottedtube in which is disposed one or more carrier rails for the runners towhich the curtain rail is to be attached, (hereinafter referred to as ofthe kind described).

In a known construction of the kind described the carrier rail and tubeare made in separate parts, but the carrier rail is fixedly arranged inthe tube. Bending of such a tube is practically impossible withoutincorrectly shaping the carrier rail. Further, in another knownconstruction in which the carrier rail has to be inserted from one endinto the tube, bending is very difficult because the insertion of thecarrier rail after separate bending is not practicable. Moreover, thecarrier rail is secured by lips pressed in the tube, or by specialbrackets engaging from outside in the tube, so that the outer surface ofthe tube is unpleasantly interrupted by the heads of nails, or screws,or incisions or brackets.

One object of the present invention is to provide a curtain rail of thekind described in which the rail and tube may be bent separately andsubsequently easily assembled.

Another object of the present invention is to provide a curtain rail ofthe kind described in which the outer tube presents a smoothuninterrupted surface.

Another object of the present invention is to provide a curtain rail ofthe kind described in which the carrier rail or rails may be readilydisconnected from and connected to the slotted tube.

According to the present invention means are provided for supporting thecarrier rail in the slotted tube which permit the rail to be insertedinto and withdrawn from the slotted tube through the slot therein.

The carrier rail may be supported in the slotted tube by a number ofsupports, the arrangement being such that the rail and the said supportscan be simultaneously inserted into or withdrawn from the slotted tube.

The supports may be in the form of brackets which can be collapsed topass them into the slotted tube and subsequently opened out when in thetube, the said brackets being supported in the tube.

In carrying out the invention the carrier rail for the runners may besupported on spring brackets or like members which can be sprung intothe tube and supported therein.

The spring brackets or like members may suitably be supported along theinner edges of the slot in the tube, the said edges being preferablycurled over to form horizontal supporting surfaces. The carrier rail andtube can, therefore, easily be again separated at any time withoutundoing screws, rivets, or the like. Moreover, the slotted tube can beseparately bent and/or formed into an angle, and, subsequently thecarrier rail,

ners 4 (Fig. 5) can roll. 3 indicates the means employed in each casefor supporting the carrier rail in the tubular casing l.

The tube l is made of iron having a brass coating, and the open edgesare curled over as at 8 to form substantially horizontal bearingsurfaces for the lower ends of the brackets 3, which are also preferablycurled over as at 9.

Referring more particularly to Figs. 1, 3, 4 and 5, the tube i is ineach case of circular crosssection.

In Fig. 1 the bracket 3 is pressed inwards at it to form a neck, so thatthe bracket can be slidden over the upper flange of the I-section.carrier rail 2, the neck H1 forming thus a supporting surface for therail 2. In Figs. 3 and 3 a tongue H is stamped out of the bracket 3 andturned downwards. The tongue II is provided with an aperture i2 by meansof which it can be secured to the end of the web of the invertedT-section rail 2 by a screw, the web of the section 2 being providedwith a corresponding screw aperture. In Fig. 4 the walls of the bracket3 are pressed together at the apex as indicated at M and the invertedT-rail 2 is connected to the bracket 3 by a screw bolt l5 passingthrough apertures in the walls M and in the web of the rail 2. In thisfigure the lower ends of the bracket 3 are curved to embrace the edges 8of the tube I and the curved ends project somewhat below the edges 8,thus forming a convenient means for inserting and removing the bracket.In Fig. 5 the upper flange of the I-rails 2 is engaged by tongues I6stamped out of the material of the brackets. This figure also shows therunners 4 in position on the lower flange of the I-rall.

In the form shown in Fig. 2 the tube I is a trough section open at thebottom. In this figure two- I-rails 2 are carried in two pairs oftongues it stamped out of the material of the brackets 3. In this figurealso one side of the bracket 3 is hingeably connected at 263 to the bodyof the bracket. In this form the bracket 3 may be made of springymaterial or otherwise. If it is not made of springy material the bracketcan be passed through the slot in the tube I by moving the side hingedat 20 around the hinge, thereby reducing the width of the bracket duringits passage through the slot.

It will be understood that the invention is in no way limited to theparticular shape of the tubes I and bracketsS shown, nor to the sectionsof carrier rails shown.

In order to mount the rail 2 in the tube I, the rail 2 is firstconnected to the brackets 3 and the assembly can then be passed into thetube 1 through the slot therein, the brackets 3 thereupon opening out inorder to be supported on the edges 8 adjacent the slot. As previouslymentioned the rail can subsequently be readily removed from the 5 tubeby pressing the walls of the bracket 3 together and drawing out from thetube. Thus the parts can readily be assembled or separated after theyhave been individually bent, or curved.

It is to be understood that the tube I may be made of any other suitablemetal or material; further, the brackets 3 and section 2 can be made ofany suitable material.

It is to be understood that all the supports or brackets 3 shown inFigs. 1 and 3-5 may be arranged to suspend more than one rail 2 in thetube I, the brackets being suitably shaped and provided with means forengaging the rails.

What I claim and desire to secure by Letters Patent is:

1. A curtain rail for runners to which the ourtain is attachedcomprising a slotted tube, a flanged carrier rail, and means forsupporting the carrier rail in the slotted tube, the rail and meansbeing insertable into and withdrawable from the slotted tube through theslot therein.
